CVE-2018-13295
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedInformation exposure vulnerability in SYNO.Personal.Application.Info in Synology Application Service before 1.5.4-0320 allows remote authenticated users to obtain sensitive system information via the version parameter.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceInformation exposure vulnerability in Synology Application Service allows remote authenticated users to obtain sensitive system information via the version parameter in the SYNO.Personal.Application.Info API endpoint. The flaw enables privilege escalation through information disclosure, potentially revealing configuration details, paths, or system specifics that should not be accessible to standard users.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if Synology Application Service is installedOn the Synology NAS, check the installed packages via Package Center or run 'dpkg -l | grep -i synology' or 'cat /var/packages/MyDS/package.info' to list installed Synology packages.Affected if Synology Application Service or related Synology package is present on the system.
-
Determine the version of Synology Application ServiceCheck the package version by inspecting the package info file at /var/packages/MyDS/package.info or via the Synology Package Center interface. Look for the version field.Affected if The installed version is lower than 1.5.4-0320 (e.g., 1.5.3-xxxx or earlier).
-
Verify the SYNO.Personal.Application.Info API endpoint exists and is accessibleIf you have CLI access, search for API configuration files containing 'Personal.Application.Info' in the Synology web directory (typically under /var/packages/MyDS/ui/). Check if the API is enabled in the package configuration.Affected if The SYNO.Personal.Application.Info endpoint is present and exposed in the API configuration.
-
Check for suspicious API queries in logsReview Synology logs (via Log Center or /var/log/messages) for access patterns to the SYNO.Personal.Application.Info endpoint. Look for repeated queries from standard user accounts that may indicate probing.Affected if Unusual or repeated queries to this endpoint are observed, especially from non-admin accounts.
A user is affected if Synology Application Service is installed with a version lower than 1.5.4-0320 and the SYNO.Personal.Application.Info API endpoint is accessible to authenticated users.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data1.5.4-0320
Upgrade Synology Application Service to version 1.5.4-0320 or later. If immediate patching is not possible, restrict API access to only trusted users and monitor for anomalous queries to the affected endpoint.
